A very rough approximation would be in the order of 1023 atoms, ie a 1 followed by 23 zeros, which is a very big number.
Given that there are over 10^21 atoms in a large grain of sand, weighing 0.03g there will be a lot more (maybe x10 or x100) in a grain of rice (which is much larger than a grain of sand). Note that rice is organic so will have a lot of hydrogen atoms as well as carbon, oxygen, nitrogen, and many others in lesser degree.
The previously stated answer of "30,000 atoms in one grain of rice" is absurd. Either the poster is testing how long it takes for an incorrect answer to be fixed or is quite ignorant of atomic dimensions (or both!).
